US 9,850,509 B2 · Oleaginous microorganism disruption process using supersonic disperser and method for producing bio-oil using same

Abstract

Provided are an oleaginous microorganism disruption process using a supersonic disperser and a method for producing bio-oil using the same. The method for producing bio-oil according to the present invention induces a cell disruption of oleaginous microorganisms without a separate drying process, thereby providing a method for continuously producing bio-oil in an economical and simple manner. In addition, the method of the present invention induces a cell disruption of oleaginous microorganisms without a heating process, thereby producing bio-oil without a change in physical properties due to the heat.

Claims13

Dependent claims

A method for producing bio-oil without a separate dewatering process, comprising:

cultivating oleaginous microorganism;
ultrasonically accelerating the cultivated oleaginous microorganism using gas supplied at a pressure high enough to disrupt the oleaginous microorganism by impinging on an impinging plate;
and extracting the bio-oil from the disrupted oleaginous microorganism wherein the high pressure ranges from 0.5 to 3 MPa.

Dependencies are inferred from the claim text.
